left. Even two of these were ultimately taken, and I suppose eaten ; I did 
not watch the whole process. The other, a D. chrysippus , was at the top 
of the cage, and possibly hard to get; I took it out. The young Babbler 
took, instead of a Danais genutia , a specimen of Nichitonia xiphia , which 
he seemed not to like. However, later on I could only find a few bits 
of wing left of all the butterflies I had put in, so I suppose it was 
eaten after all. The birds had had some grasshoppers first. 
III. Put a Danais genutia into the aviary, where a Babbler took 
it and ate it whole. A D. chrysippus was taken by a Babbler, which 
was pulling off the wings with no great eagerness, when another took 
it away and ate the body. An Euploea (rather crushed) was eaten 
readily enough, with part of the wings, by a Babbler. I then put 
in several D. chrysippus and genutia , and the birds ate them all and 
fought over them. I saw one throw up a body two or three times before 
swallowing it, AD. chrysippus was first taken when I put in two of 
each kind (D chrysippus and D. genutia) dead. The birds had had 
some grasshoppers some hours before. Some time afterwards I killed 
and put in— 
(a.) One each of Danais chrysippus , genutia , and limniaGe , Euploea, 
and Catopsilia. A bird snatched the D. limniace before I 
took my hand away, and the Catopsilia was not, I think, 
the next taken. The Euploea was swallowed whole. 
(h.) Two D. chrysippus and a large brown species put in; a bird 
first took the latter. 
(c.) The same two D. chrysippus were put in together with a 
Junonia. Two birds advanced at once and one took the 
Junonia , the other a D. chrysippus. The Junonia was 
eaten before my eyes, and I saw the other begun upon. 
( d .) I repeated this experiment with two D. chrysippus and another 
protectively-coloured specimen. This latter was taken by 
the first bird which came. About this time I saw a bird 
eat the body of a Danais , and soon found two lying about. 
The birds pecked but did not seem to care for them. 
(e.) I put in a Catopsilia and two D. chrysippus ; two or tliree 
of the birds came at once. One took the Catopsilia and 
another a D. chrysippus. 
(/.) Putina Catopsilia and one D. chrysippus. The first comer 
took the former, and immediately afterwards the latter 
was taken. The Catopsilia was eaten at once with some 
of its wings. The body of the other was eaten after 
some rubbing ; I do not know whether the eater was the 
individual which look it.
